Swann 8 Channel DVR H.264 - Manual (Page 50)

48 Remember: After making changes to the settings press/click the APPLY button.
Buzzer: Whether the internal alarm speaker inside the DVR is enabled
or not. When set to OFF, the buzzer will not sound under any
circumstances.
You can choose which types of alarm events will trigger the buzzer
by selecting or deselecting the first tick box next to the type of
alarm event you want to trigger the buzzer.
We suggest leaving the buzzer enabled, and having it sound on
HDD Loss, HDD Space and Video Loss alarm events. This way, the
DVR will give you a warning if its operation is compromised (either
it is unable to record more footage, or there is no incoming video
feed to record).
MD Alarm: Whether the DVR’s Motion Detection function will trigger an alarm
event. Note that this can be set independently of the Motion-based
recording, which is controlled via the Schedule (page 25) and
motion detection configuration (page 27) menus.
HDD Loss: Will trigger an buzzer/email if the hard drive stops functioning.
HDD Space: Will trigger an buzzer/email when the hard drive is out of space.
Video Loss: Will trigger an buzzer/email when a camera stops supplying
images.
Email: See “Auto Email Setup Menu” on page 49.
Post-Recording: How long the DVR will continue to record after an alarm event
(such as motion) occurs.
Pre-Record: Allows the DVR to save a short amount of footage taken before
an event actually occurs. This can be particularly useful for video
loss alarms, as you might just catch who or what caused this alarm
event!
